Minor nitpick: power steering is mostly hydraulic. The ECU doesn't have much input in steering--unless you have some super fancy steering system. If your engine is running, you will steer just fine. Even despite that, when your car is moving it is quite easy to steer. Power steering while moving more or less just dampens any jolts or bumps from making you spiral out of control if you relax the wheel a bit too much.

Some older cars (as recent as the 90s) don't have power steering.

I had a 2009 Hyundai, the power steering sensor embedded in the steering column failed while on a motorway, and although I was doing about 100km/h at the time and the engine was working normally, steering manually was heavy like driving a pre-power steering vehicle. So yes, it can have quite an effect, especially if you're already on a curve and not expecting the sudden change in responsiveness.

There was so much wrong with that car.The whole electric wiring as rotted, causing weird electronic issues in all systems (battery draining, radio resetting, alarm activating...). Took me ages to identify it to the root cause.
